* This DTC may be set with a misfire DTC, however the existence of this DTC is a higher priority and indicates the condition to diagnose is

related to fuel and/or injectors, not the ignition/spark system.

* A restricted fuel injector may cause this DTC to set.

* High resistance in the circuits of the injectors could set this DTC without setting an injector DTC. Test the injector circuits of the affected

cylinders for a high resistance if you suspect a condition.

* A drop in system voltage during cold start may set this DTC.

Circuit/System Testing

Note: Circuit/System Testing requires cold start. Do not start vehicle prior to connecting scan tool and preparing to evaluate the condition during

engine crank.

1. Start the engine and observe the Cylinder 1-4 Current Misfire Counters during the first 500 engine cycles. The Cylinder 1-4 Current Misfire

Counters should not be incrementing.

瀚慖f the misfire counters are incrementing on one or more cylinders, verify that the following conditions do not exist:

* Fuel pressure that is too low or too high-Refer to Fuel System Diagnosis (LF1 China) (See: Powertrain Management/Fuel Delivery and

Air Induction/Fuel Pump/Testing and Inspection/Fuel System Diagnosis (China))Fuel System Diagnosis (LF1 Except China) (See:

* Contaminated fuel-Refer to Alcohol/Contaminants-in-Fuel Diagnosis (Special Tool) (See: Powertrain Management/Fuel Delivery and

Air Induction/Fuel/Testing and Inspection/Alcohol/Contaminants-in-Fuel Diagnosis (Special Tool))Alcohol/Contaminants-in-Fuel

Diagnosis (Without Special Tool) (See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Component

Tests and General Diagnostics/Alcohol/Contaminants-in-Fuel Diagnosis (Without Special Tool)).

2. If all conditions test normal, replace fuel injectors as indicated by high misfire counts.

Repair Verification

Note: Repair Verification requires cold start.

1. Ignition ON, engine OFF, clear the DTCs with a scan tool.
